Hi! This is a more pgsql-general list question.
Objects that created during extension install script will be owned by
superuser (except when extension control file uses superuser=false)
Try this:
create extension dblink ;
then
select * from pg_depend where deptype = 'e' and refobjid = (select oid
from pg_extension where extname = 'dblink');
You will see a bunch of functions, types and foreign server objects,
all owned by superuser.
For example, for foreign server you can verify it like this:
db2=> select fdwowner from pg_foreign_data_wrapper where fdwname = 'dblink_fdw';
fdwowner
